[HBASE-10923] Control where to put meta region

• Type: Improvement

Release Note

This patch introduced a new configuration "hbase.balancer.tablesOnMaster" to control what tables' regions should be put on the master by a load balancer. By default, we will put regions of table acl, namespace, and meta on master, i.e. the default configuration is the same as "hbase:acl,hbase:namespace,hbase:meta". To put no region on the master, you need to set "hbase.balancer.tablesOnMaster" to "none" instead of an empty string(the default will be used if it is empty).

Description

There is a concern on placing meta regions on the master, as in the comments of HBASE-10569. I was thinking we should have a configuration for a load balancer to decide where to put it. Adjusting this configuration we can control whether to put the meta on master, or other region server.
